Description_x000D_ General description_x000D_ Solute carrier family 38 member 9 (SLC38A9) is encoded by the gene mapped to human chromosome 5q11.2. The encoded protein belongs to the family of SLC38 and is ubiquitously expressed. SLC38A9 is localized to lysosomal membranes._x000D_ Immunogen_x000D_ solute carrier family 38, member 9 recombinant protein epitope signature tag (PrEST)_x000D_ Application_x000D_ Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below._x000D_ Western Blotting (1 paper)_x000D_ Physical form_x000D_ Solution in phosphate buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide._x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Legal Information_x000D_ Prestige Antibodies is a registered trademark of Sigma-Aldrich Co. LLC_x000D_ Biochem/physiol Actions_x000D_ Solute carrier family 38 member 9 (SLC38A9) is a lysosomal amino acid transporter, which plays a vital role in transducing amino acid availability to mammalian target of rapamycin complex 1 (mTORC1) activity. Elevated expression of SLC38A9 makes mTORC1 signaling insensitive to amino acid starvation but not to recombination activating gene (Rag) activity._x000D_ Features and Benefits_x000D_ Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section._x000D_ Every Prestige Antibody is tested in the following ways:_x000D_ • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues._x000D_ • Protein array of 364 human recombinant protein fragments._x000D_ • Validated for multiple commonly used applications such as IHC (Immunohistochemistry), IF (Immunofluorescence), and WB (Western Blot)_x000D_ Linkage_x000D_ Corresponding Antigen APREST84147.
